I spent all day yesterday making macros and dialogs for a financial spreadsheet I'm working on. I saved several times throughout the day using either File>Save or ctrl+s and even did a File>Saveas to make a backup copy. At 1:30 am, I did one final save and closed down for the night. At 9:30 am, I opened the spreadsheet and though the spreadsheet was as I had left it at 1:30 am, the macros were gone. I opened the original and the same thing. The macros were not there; in both files, the macros were the way they had been when I started yesterday morning. Everything from yesterday was gone.
I followed the roaming path to get to the autosaves and temps and there was nothing listed in either since last year! I know autosave has been working, it kept interrupting me throughout the day yesterday but nothing was saved in there.
I've lost everything. Why? And is there any chance to recover this?
